The invention relates to pinch valves for opening and overlapping of the working fluid flow, and can be used in medical engineering, for example in apparatus for extracorporeal blood purification. Pinch valve comprises a housing installed inside the thrust electromagnet with a magnetic core, a spring disposed between the housing and the yoke is rigidly fixed to the magnetic core, the core strip with the presser foot and the base mounted on the end surface of the housing, the pinch tube is located in the recess between foot and the base. The technical result consists in improving the reliability of operation of the valve, reducing its size and power consumption and excluding negative consequences for the patient receiving blood purification procedure is achieved in that the valve additional retaining electromagnets installed interacting with clamps fastened to the yoke, in front of the presser foot spring-loaded tab mounted to move longitudinally in slots of the base plate are placed tight contact with the tube and capable of longitudinal movement, the opposite end of which is connected to a spring-loaded rod element, at the end of which is rigidly mounted box, in front of which is placed a sensitive sensor element on the beam is placed a similar box, opposite which is also located sensor the second sensor, wherein the sensors are electrically connected with a control unit. 1 yl.Полезная модель относится к пережимным клапанам, предназначенным для открытия и перекрытия потока рабочей среды, и может быть применена в медицинской технике, например в аппаратах для экстракорпоральной очистки крови. Пережимной клапан содержит корпус с установленной внутри него толкающим электромагнитом с магнитным сердечником, пружину, установленную между корпусом и коромыслом, жестко закрепленным на магнитном сердечнике, удлинитель сердечника с прижимной лапкой и основание, установленное на торцовой поверхности корпуса, при этом пережимаемая трубка располагается в пазе между лапкой и основ
